Overview
The Fenner Drives 6202865 is a Trantorque GT series keyless bushing designed for secure, backlash-free mounting of components on 40mm diameter shafts. This steel locking device eliminates the need for traditional keys while providing a robust mechanical interference fit suitable for high-torque, thrust, bending, and radial load applications. Its single-nut locking design and interlocking components ensure positive engagement and release in demanding motion control and power transmission environments.
Key Features
- Zero-backlash frictional connection that will never wear or pound out
- Accommodates high-torque, thrust, bending, and/or radial loads
- Keyless bushing suited to critical timing and high-torque applications
- Single-nut design with interlocking components for positive locking and release
- Steel construction for durability and wear resistance
- 40mm shaft diameter with 67mm outside diameter for compact integration
Technical Specifications
The Fenner Drives 6202865 specifications include a robust torque transmission capacity of 728 Nm, installation torque of 317 Nm, and thrust rating of 34 kN. The unit weighs approximately 2.65 lbs and features self-centering capability for accurate component positioning. Material data multipliers are available for alternative finishes including electroless nickel plating, hard chrome coating, and stainless steel.
